If you are allergic to plastic, we recommend kybun sandals (their insoles are made of leather), or you can use a thin leather insole for closed shoes.
Some parts in the middle lining of the shoes are glued with latex adhesive. Although these areas do not come into direct contact with the skin, we cannot eliminate the possibility that there is latex adhesive on other parts of the shoe.
We rarely use rubber parts and in cases where we do, it is only on the outer part of the shoe, for example, the Baekdu. Direct contact with the skin is not possible here.
The mesh (material used) is treated with Zeolite for antibacterial effect.
